网站的查看部分需要很长时间才能加载

Question

我正在使用PHP，Smarty和MySQL开发一个网站。加载网站的视图部分需要很长时间。我可以快速地从数据库中获取和查看数据，问题在于显示部分。

http://jobsgang.com/c0b0dfc2379f0379d546b727/Kerala_jobs/Kozhikode_jobs/Other_Places_in_Kozhikode_jobs/Engineering_Projects_jobs/Engineer_jobs/btech_be_jobs/experienced_jobs/permanent_jobs/We_are_looking_for_Fresh_Talented__Project_Management_Tranies.html

你可以在这里看到来自php的数据。它会加载很快，但网站的显示部分需要很长时间。

请帮我解决一下

Answer 1

这与PHP无关，你在该页面上有一些Crazy ajax调用，就像每秒调用一个不存在的页面一样。

删除以下脚本

 <script type="text/javascript" src="http://s7.addthis.com/js/300/addthis_widget.js#pubid=xa-506aa6a401ec5bef"></script>

Answer 2

这是Chrome的结果，也是来自它的建议，

**Combine external JavaScript (6)**
There are multiple resources served from same domain. Consider combining them into as  
few files as possible.
6 JavaScript resources served from epbkomalpdcfielganbfombgchcdebfg.

**Enable gzip compression (13)**
Compressing the following resources with gzip could reduce their transfer size by about    
two thirds (~638.28KB):
css could save ~188B
container.html could save ~4.37KB
container.css could save ~23.98KB
jquery.js could save ~66.14KB
jsonStringify.js could save ~3.96KB
jquery-ui.custom.js could save ~304.30KB
jquery.additions.js could save ~2.05KB
jquery.batchImageLoad.js could save ~1.44KB
container.js could save ~196.65KB
chrome-extension://epbkomalpdcfielganbfombgchcdebfg/initData.json could save ~1.29KB
xd_arbiter.php could save ~16.80KB
xd_arbiter.php could save ~16.80KB
about.css could save ~305B

**Leverage browser caching (18)**
The following resources are explicitly non-cacheable. Consider making them cacheable if    
possible:
We_are_looking_for_Fresh_Talented__Project_Management_Tranies.html
container.html
container.css
jquery.js
jsonStringify.js
jquery-ui.custom.js
jquery.additions.js
jquery.batchImageLoad.js
container.js
chrome-extension://epbkomalpdcfielganbfombgchcdebfg/initData.json
endSeperator.gif
expend.png
arrow_down.png
addApp.png
seperator.png
xd_arbiter.php
xd_arbiter.php
about.css

**Leverage proxy caching (5)**
The following publicly cacheable resources contain a Set-Cookie header. This security   
vulnerability can cause cookies to be shared by multiple users.
style.css
pagination.css
jquery-1.4.2.min.js
ajaxSignUp.js
all.js

**Minimize cookie size**
The average cookie size for all requests on this page is 27B

**Specify image dimensions (1)**
A width and height should be specified for all images in order to speed up page   
display. The following image(s) are missing a width and/or height:
lock.png (5 uses)
Web Page Performance
**Optimize the order of styles and scripts (4)**
The following external CSS files were included after an external JavaScript file in the   
document head. To ensure CSS files are downloaded in parallel, always include external   
CSS before external JavaScript.
about.css
3 inline script blocks were found in the head between an external CSS file and another   
resource. To allow parallel downloading, move the inline script before the external CSS   
file, or after the next resource.

**Remove unused CSS rules (510)**
78.97KB (88%) of CSS is not used by the current page.
style.css: 17.28KB (78%) is not used by the current page.
pagination.css: 692B (76%) is not used by the current page.
Inline block #1: 3.63KB (88%) is not used by the current page.
Inline block #2: 11.95KB (85%) is not used by the current page.
about.css: 447B (100%) is not used by the current page.
container.css: 31.69KB (92%) is not used by the current page.
Inline block #3: 28B (11%) is not used by the current page.
Inline block #4: 13.28KB (98%) is not used by the current page.

**Use normal CSS property names instead of vendor-prefixed ones (6)**

看看红色的文字，

Answer 3

由于视图部分需要花费很长时间才能进行调试：

如果您正在使用Smarty并且要渲染许多模板 - 这可能是一个原因。尝试在smarty中打开缓存。

同时打开smarty调试控制台并检查渲染是否需要花费大量时间。

Answer 4

<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
